Chapter 198 Brother Pit’s Sister

After hanging up the phone, Xu Chuan was startled when he turned around.

Three friends stood behind him and eavesdropped.

"Brother Chuan, is it my sister-in-law calling? Tell me the truth!"

"I heard a female voice!"

"Bring her here, and ask my sister-in-law to come over quickly so we can get to know her."

The three of them talked at once, and Xu Chuan couldn't help rolling his eyes. He ignored the group of friends who were obsessed with eating melons and walked back to the table.

Skipping this topic, the four of them clinked glasses in succession, and after drinking two bottles of beer, the topic gradually opened up.

Sometimes they talked about arrangements after graduation, sometimes about games, and sometimes they would shift to things happening at home and abroad.

For example, a female college student from a certain school stole headphones and was not only not punished, but was admitted to graduate school.

For example, a star participated in idol trainees and released a self-introduction video. He became popular because he practiced for two and a half years and played basketball in suspenders.

It's still quite a long time for college students not to see each other for nearly a year.

Unlike entering society, it's not uncommon to not see each other for a few years or even for a lifetime.

The meal lasted two hours before the four of them dispersed, agreeing to meet again when the three of them graduated.

Xu Chuan returned to the hotel arranged by NCU. He did not forget to have dinner with his senior sister in the evening. He took a shower to get rid of the smell of alcohol and took a nap to rest.

The alarm clock woke him up at the appointed time in the afternoon. He stretched and got up from the bed. Xu Chuan touched his phone and looked at the time. It was almost four o'clock.

He turned on the computer to deal with the emails in the mailbox and replied to some messages. Then he got up and came to Xiaoxianzhuang at the gate of NCU again.

Just as he was about to send a message to the senior sister to ask her when she could come, a familiar figure sitting by the window came into his sight.

Walking quickly, Xu Chuan smiled and shouted: "Senior sister."

"You are here."

The senior sister who was reading with her head down raised her head after hearing the voice. When she saw Xu Chuan, a trace of joy appeared in her eyes.

"Sorry to keep you waiting." Xu Chuan said embarrassedly. He thought he should be the first one to arrive, but he didn't expect that the senior sister arrived earlier.

"It's okay, I just got here a while ago." The senior sister whispered, closing the book in her hand and putting it on the table.

Xu Chuan glanced at the book that the senior sister closed and put on the table. The "Introduction to Algorithms" on the cover made him smile with relief.

With his original advice and the bonus of the tungsten diselenide research project, the senior sister finally embarked on the path of further study and achieved excellent results.

I have to say that he is quite accurate in judging people.

At the beginning, he felt that this senior sister had great potential for further study in academia, and now the facts have proved this.

Maybe the difficulties in life have been solved and she no longer needs to work part-time day and night. She has exploded with great potential in her studies. Just after entering the third year, she has completed her undergraduate studies and entered the postgraduate study stage.

Now more than a year has passed. Occasionally, I heard from Professor Zhou Hai that she has almost finished her postgraduate studies and is preparing to apply for a doctoral degree.

It took two years to complete the undergraduate course and more than a year to complete the postgraduate study. This speed can be said to be quite fast.

Xu Chuan sat down and asked, "Have you ordered yet, Senior?"

"Not yet." Senior shook her head.

Hearing this, Xu Chuan waved to the waiter in the store and shouted, "Waiter, order."

Soon, a waiter came over. Coincidentally, it was the auntie who came at noon.

After seeing Xu Chuan, her eyes lit up and said, "Young man, you are too late. Your girlfriend has been waiting here for at least half an hour. Even if you are a great scientist, you must remember to be on time for a date."

Xu Chuan was stunned for a moment and glanced at the senior.

Didn't you say you just arrived a while ago? What does more than half an hour mean? It's not even half past five now, which means she came at more than four o'clock?

The senior was stunned for a moment after being exposed by the waitress.

Xu Chuan smiled, looked at the waitress, and said, "Sorry, I will pay attention next time. Let's order first."

Speaking of which, this waitress has known them for a long time. He met him and the senior when he first ate here when he was in Nanjing University. I just didn't expect that she would still remember it after so long.

After ordering the dishes, Xu Chuan looked at the senior and asked, "Which field do you plan to study in your doctoral degree?"

Liu Jiaxin: "Mathematical algorithms and artificial intelligence."

"Very good, these two fields will be very popular in the future. As long as you have the ability, it is not difficult to earn tens of millions a year."

Xu Chuan replied with a smile. Hearing about these two fields, he knew that the senior had probably carefully studied his previous opinions and the development of the industry.

Although earning tens of millions a year sounds exaggerated, it is not that he is bragging.

For the top experts in the fields of mathematical algorithms and artificial intelligence, it is a small number to say that they earn tens of millions a year.

For example, a certain audio that will gradually become popular next year, its algorithm experts have been offered an annual salary of over 100 million by the United States in the future.

This shows the potential of this industry.

In the future, the fields of algorithms and artificial intelligence will be the hottest development prospects. After all, the era of big data cannot do without these two.

Hearing this, Liu Jiaxin's cheeks turned a little red. At the beginning, she thought that an annual salary of 200,000 or 300,000 was already exaggerated.

Ten million? That is even more unthinkable.

"Are you still going to study at Nanjing University for your doctoral degree?" Xu Chuan asked curiously.

Although the mathematics department of Nanjing University is not very good, the computer science major is quite good.

Although the scale is not large, it is taking the high-tech path.

In core fields such as software, AI, system architecture, and data mining, it is one of the best in China, and the quality of scientific research output is extremely high.

Liu Jiaxin nodded and continued: "But I applied to my tutor for an exchange student quota for Princeton. The tutor said that Princeton's computer science is strong in artificial intelligence and algorithms, and these two fields are inseparable from mathematics. I want to learn about mathematics as well."

Xu Chuan was stunned for a moment, and then said: "It seems that your academic performance is much better than I thought."

He was right. Princeton University not only has a few doctoral students from China in the mathematics department in a year, but also has a computer science department. The number of students in China in a year can be accepted by one hand.

Although the computer science department of Nanjing University is not ranked very high in China, it is one of the only three domestic universities that has a first-level key computer discipline, a national key laboratory, a double first-class world-class discipline, and a national top-notch base.

Although Princeton has few places for exchange students, it is not without them.

However, it is quite difficult to apply for an exchange student place. If you cannot be in the top five of this subject, you basically cannot get this place.

So he sighed that the senior sister's grades were much better than he thought.

After a pause, he continued: "It's also good to study at Princeton. Although Princeton's computer science is not as good as mathematics and physics, it is also quite good."

"And your study direction, mathematical algorithms and artificial intelligence, are both excellent subjects there, and you can learn a lot."

The senior sister nodded vigorously and said seriously: "I will work hard."

Xu Chuan smiled and said: "Come on."

After staying in Nanjing University for five days, Xu Chuan set off to go home.

On the one hand, he had to go through the ceremony to accept the title of honorary professor of Nanjing University, and on the other hand, he had to accept the award ceremony of Nanjing University, the city, and the province.

After all, people have given you money, so it is necessary to go through the process and let the media take a few photos to cooperate with publicity.

On the other hand, in addition to giving a speech to the younger students of Nanjing University, he also needs to hold a report meeting at Nanjing University.

This was something he had agreed to long ago.

As for the content of the report, it was undoubtedly the Hodge conjecture.

In fact, he received many invitations for this type of report.

Whether it was domestic or foreign, many universities and even some scientific research institutions sent him invitations, asking him to give a report or a speech.

The highest remuneration offered by one university was even 300,000 yuan.

But Xu Chuan refused most of the reports or speeches, leaving only domestic invitations.

On the one hand, he did not have so much time to run around and give speeches.

On the other hand, it was because he was a Chinese, a student of Nanjing University.

Although the development of mathematics is gradual, a report cannot immediately improve the development of the domestic mathematics community, but it can still play a role.

As a top scholar in this field, if he is willing to spread knowledge in this area, he can still play a lot of roles.

Although this role may take several years or more than ten years to fully manifest.

But the subtle influence is there and will not fly away.

After dealing with the things in Jinling, Xu Chuan bought a ticket and took the high-speed rail from Jinling back to Xingcheng.

Although it is faster to take a plane, it is not much faster.

It is very troublesome to go through the various procedures of entering the station, checking tickets, and waiting for the flight.

In China, if the high-speed rail journey is less than five hours, from departure to exit, the high-speed rail is actually not much slower than the plane.

And more importantly, the high-speed rail is more comfortable and gives people a sense of security than the plane.

After all, it is running on the ground. If something happens, there is still a glimmer of hope, but if something happens on the plane, it is really helpless.

Dragging the suitcase, Xu Chuan went to Xingcheng No. 1 Middle School.

Before returning to his hometown, he had to go to No. 1 Middle School to pick up Xu Xiao.

For this, Xu Xiao spent a long time on the phone.

Although he didn't know why the girl insisted on him to pick her up, after a long time, he finally couldn't bear it and agreed.

It's okay to go and see Lao Tang on the way.

Xu Chuan has always been grateful to Lao Tang.

After all, there are so many geniuses in this world? But how many of them have really come out.

He and Old Tang are the real-life version of a Thousand-Li Horse and a Horseman.

If he hadn't been discovered and taught by this high school teacher in his previous life, he would have most likely been lost in the vast sea of ​​people.

Standing at the school gate, Xu Chuan took out his mobile phone and called Old Tang.

Hearing that he was at the gate of No. 1 Middle School, Old Tang didn't come back to his senses for a while. He was stunned for a long time and repeated confirmation before quickly hanging up the phone.

After a while, Old Tang appeared at the school gate and took him into the school.

"You kid, why didn't you call in advance before coming here." Seeing Xu Chuan, Old Tang complained.

Xu Chuan smiled and said, "It's not a big deal."

Old Tang glanced at him and said, "Why is it not a big deal? A Fields Medal winner comes in person, and every school has to welcome him, right?"

Xu Chuan smiled and said, "I haven't got it yet."

"If you prove the Hodge conjecture, I will take your last name if you can get the Fields Medal next year!" Old Tang said with disdain.

"Should I call the Fields Prize jury and ask them to postpone the award for four years?" Xu Chuan joked with a smile.

Hearing this, Old Tang glanced at him again: "Say it again if you have the guts?"

Xu Chuan quickly admitted his weakness and said: "No, no."

"But speaking of it, your silent proof of the Hodge conjecture really shocked many people."

Old Tang sighed and continued: "Although I know that you are talented in mathematics, this is too exaggerated."

Xu Chuan: "It's just an occasional inspiration."

"Okay, don't be modest." Old Tang rolled his eyes and took him to the teaching building.

"By the way, teacher, when is the winter vacation?" Xu Chuan asked Old Tang.

"The first and second grade students have already had their winter vacation, and the third grade students will have their winter vacation the day after tomorrow. You came here to pick up your sister this time, right?" Old Tang asked.

"Of course, I also visited you, teacher." Xu Chuan laughed.

"Heh, you are still a human being." Old Tang snorted, as if he remembered something, staring at Xu Chuan and continued: "Speaking of which, you have a good sister, who looks exactly like you."

Xu Chuan laughed dryly and knew what Old Tang was talking about.

"Brother!"

In Class 1401, after seeing the figure at the teacher's door, Xu Xiao jumped over excitedly.

Xu Chuan smiled and rubbed the girl's head, saying, "Tell me, why do I have to go there in person? Can't you take a taxi home? Your brother's schedule is very tight."

Xu Xiao wrinkled his nose, held his hand and shook it, saying, "You are my brother. What's wrong with coming to pick up your dearest sister during the winter vacation?"

Xu Chuan glanced at her and said suspiciously, "That's it?"

Xu Xiao vowed, "What else?"

As soon as she finished speaking, a classmate came over, looked at Xu Chuan, then looked at Xu Xiao, and said blankly, "Are you really coming?"

Xu Chuan asked in confusion, "What are you really coming?"

Hearing this, the classmate reacted and said, "Xiao Xiao made a bet with me before, saying that she could let you pick her up. The loser will learn, breakfast"

Before the girl finished speaking, Xu Xiao rushed up and covered her mouth.

But Xu Chuan still heard something, and looked at Xu Xiao who was playing around with a black line on his face.

This sister can't be kept.

After picking up Xu Xiao smoothly, the two dragged their suitcases and took a taxi back to their hometown, no, it should be said that they had a new home.

Under his repeated persuasion, Xu's father and mother finally moved from the original two-story building to the villa built last year.

They had never wanted to live there before.

In the eyes of Xu's father and mother, the villa was a new home for Xu Chuan to use when he got married in the future. Why did they move there? It's not like they couldn't live in the old house.

Parents are always like this, always wanting to leave the best things to their children.

But in the end, Xu Chuan still convinced his parents. After all, houses are built for people to live in. Why build houses that are not inhabited? Just put them there for show?

And to be honest, there is a big difference between rural houses with people living in them and houses without people living in them.

Houses that are not inhabited, even if they are newly built, will age very quickly.

Just like the houses left behind by those five-guarantee households after their death, they would collapse after a year or two.

When they were alive, those old houses, even the earthen houses made of loess embryos, could withstand wind and rain without any problems.

In rural areas, this kind of thing is called "popularity". Only houses with people living in them have popularity. If no one lives in them, God will take them away for you.
